Eco-Recycled Fabric. We take existing plastic rubbish, largely from discarded plastic water bottles, and break them down to create fine thread fibers that are then blended with our 4-way stretch swim fabric. This fabric is still flexible, durable, doesn’t take on a ton of water, dries quickly and is still comfortable to the touch. This 4-way stretch technology board shorts let your little man run and play in or out of the water. This performance fabric is lightweight, stretchy, soft to the touch and fast to dry. Features: * An inner belt that expands/contracts to help accommodate growing little bodies. * Stretch-flap fly to make it easy to get on and off with a small patch of Velcro to keep in place. * Back pocket with eyehole for an easy flow of water. * Recycled blend 4-way stretch fabric. 92% Polyester / 8% Spandex A LITTLE FEEDBACK BASED ON FAQ ABOUT SIZING.
